Advantages

High precision:

Pressure casting allows the production of parts with complex shapes and high dimensional accuracy.

Excellent surface quality:

The parts have a smooth surface finish and typically do not require additional processing.

High efficiency:

Short production cycles make it well-suited for mass production.

High material utilization:

Efficient use of molten metal results in minimal waste.

Lightweight:

Ldeal for manufacturing lightweight components, especially those made from aluminum and magnesium alloys.

Materials

Aluminum alloy:

The most commonly used die-casting material, characterized by light weight, high strength, and good corrosion resistance. Widely used in the automotive, aerospace, and electronics industries.

Magnesium alloy:

Lightweight yet strong, ideal for producing lightweight parts. Commonly applied in automobiles, aerospace, and 3C (computer, communication, and consumer electronics) products.

Zinc alloy:

Offers good fluidity and a high-quality surface finish, making it suitable for manufacturing precision parts. Commonly used in hardware, decorative components, electronic housings, and more.

Copper alloy:

Known for excellent electrical and thermal conductivity, though relatively expensive. Mainly used in electrical components, radiators, and similar applications.

Processing Technology

Mold design and manufacturing: The mold is designed based on the shape of the part. It is typically made of high-strength steel and consists of two parts: a fixed mold and a movable mold.

Metal smelting: The metal material is heated to a molten state and maintained at a stable temperature.

Molten metal injection: The molten metal is injected into the mold cavity under high pressure using an injection system (such as an injection cylinder and injection head).

Cooling and solidification: The molten metal rapidly cools and solidifies inside the mold.

Mold opening and part removal: The mold is opened, and the solidified parts are removed.

Post-processing: Includes deburring, surface treatments (such as polishing or spraying), and dimensional inspection of the parts.
